Your source is a vital records entry for the marriage of Nathaniel's parents, who are identified in the profile, apparently based only a secondary source. By adding your sourced info to the profile, you will be improving its quality. This is the kind of thing we hope will happen to profiles like that one. 
Also, the profile for the father, Robert Clement, is completely unsourced, and there is no profile for the mother. Adding this source to the father's profile would be a great improvement. Furthermore, even though this marriage record may be the only piece of evidence we have for the mother, it would be a sufficient basis for creating a profile for her (with a realistic guesstimate for her year of birth). There are some other Odiornes recorded in colonial Massachusetts -- she probably is related to at least one of them, but we don't need to identify parents or siblings in order to create a profile for her.
